The Patriots practiced in the middle of Winter Storm Hercules this morning on the Gillette Stadium game field.

Wide receiver Austin Collie re-signed with the team in time for the workout, which might not be a terrific sign for the health of rookies Aaron Dobson and Josh Boyce. Dobson hasn't practiced this week since aggravating the stress fracture in his left foot, and Boyce hasn't practiced since injuring his ankle against the Dolphins in Week 15.

Left guard Logan Mankins (ankle) and cornerback Alfonzo Dennard (knee, shoulder) were also absent for the second straight day. Mankins injured his ankle Sunday and missed one series in the second quarter, and Dennard was held out of the regular-season finale.

Collie's presence had to cost someone a roster spot. Since every practice squadder was accounted for at practice, it could mean one of the absentees was placed on injured reserve.
